Just remembered back in the 80s we used to throw a big pair of home stereo speakers in the back of the Vega,as big as would fit with an extra equalizer amp up front what a sound that was!
Thought I lost a box with all the trim and headlight/marker stuff but found it in the shed rafters after so long,sweating on that one.Really blessed on the excellent condition most every thing still is.
Rear seat hardware also bagged up together in there and they need a little attention.
Fhix rust remover
scrub until surf rust gone
couple coats of clear protectant
also wet sanded the rubber stoppers with 400 grt to get them back to factory gray color
nothing exciting but guess it makes a difference
